Hi Susan,
I modified the stylesheet to display the titles on first occurence in the table,
This is the output I get now:
doc-number title description arrival-date
53690 American Artist v.68:no.738(2004:Jan.) 02/26/2004
57769 The American city & country v.119:no.3(2004:Mar.) 03/25/2004
57769 v.119:no.1(2004:Jan.) 02/11/2004
58345 American demographics v.26:no.3(2004:Apr.) 04/12/2004
58345 v.26:no.2(2004:Mar.) 03/06/2004
58345 v.26:no.1(2004:Feb.) 02/05/2004
58615 Forbes. v.173:no.5(2004:Mar.15) 03/15/2004
58615 v.173:no.2(2004:Feb. 02) 01/21/2004
58615 v.173:no.1(2004:Jan. 12) 01/12/2004
I added a key:
<xsl:key name="titles" match="//section-02/title[string(.)]"
use="../doc-number"/>
And then instead of directly writing to the table, I created another global
variable,
already sorted, structured like
<output>
<title doc-number="53690" title="American Artist"
description="v.68:no.738(2004:Jan.)" arrival-date="02/26/2004"/>
<title doc-number="57769" title="The American city & country"
description="v.119:no.3(2004:Mar.)" arrival-date="03/25/2004"/>
<title doc-number="57769" title="The American city & country"
description="v.119:no.1(2004:Jan.)" arrival-date="02/11/2004"/>
<title doc-number="58345" title="American demographics"
description="v.26:no.3(2004:Apr.)" arrival-date="04/12/2004"/>
...
</output>
where every record has its full title.
Then, when writing the output in the table, I only print the title if it's the
first
occurence of that doc-number.
